Title: DHCP Vendor-Specific Options for Different Devices

DHCP Vendor Identifiers

Different devices use specific vendor-specific options in their DHCP requests. These options help the DHCP server identify the type of device and provide the correct configuration parameters. For example, MSFT 5.0 is used by Windows computers, dhcpcd-5.5.6 is used by Android devices.

Vendor Class Identifier

The vendor class identifier is a field in the DHCP request that identifies the vendor of the client device. This value is used by the DHCP server to determine the appropriate vendor-specific options to send to the client.

Client Vendor Name

The client vendor name is a field in the DHCP request that identifies the specific model or type of client device. This value is used by the DHCP server to provide more specific configuration parameters.

Windows Client Vendor Options

Windows clients use the option 60 field in the DHCP request to specify the vendor-specific options they require. The value of this field for Windows clients is MSFT 5.0.

Android Client Vendor Options

Android clients use the same option 60 field in the DHCP request to specify their vendor-specific options. The value of this field for Android clients is dhcpcd-5.5.6.

Example: DHCPv4 Client Configuration

The following is an example of how a DHCPv4 server can be configured to send vendor-specific options to a client:

1. The administrator configures the DHCPv4 server to send Vendor-specific Options to the client.
2. The DHCPv4 client joins the network and sends a DHCPDISCOVER message that includes the vendor class identifier and client vendor name.
3. The DHCPv4 server receives the DHCPDISCOVER message and identifies the client as a Windows computer.
4. The DHCPv4 server sends a DHCPOFFER message that includes the vendor-specific options for Windows clients.
5. The DHCPv4 client accepts the DHCPOFFER message and begins using the vendor-specific options.

By understanding the different vendor-specific options used by different devices, network administrators can ensure that their DHCP servers are configured to provide the correct configuration parameters for all clients on the network.
